At work we've decided to do away with our home grown intranet and upgrade it to Sharepoint Portal Server 2003. I like the idea plus I'm going to be on the team to get it up and running - nothing wrong with playing with some new technology. Anyway, Andrew Connell has a list of Sharepoint Resources and a Sharepoint MVP Blog Directory. I know I'll being reading over this in the coming weeks.
I've installed and coded for Plumtree Portal for a client but this will be my first attempt at Microsoft's product. I'm pretty excited to see what they have in common and how they are different.
